Abstract:
in the context of the international debate surrounding the under-representation of women in the sciences, unleashed by the ex-president of harvard university, this paper presents a case study from a research center in southeastern mexico. institutional databases tracking academic productivity were analyzed and a survey was conducted among researchers with regard to how they use their time, their degree of satisfaction with work and home life, gender relations, and how they cope with multiple activities. there was no significant difference in productivity between men and women, even though the latter dedicate more time to housework and child care. both personal and institutional strategies to promote balance between academic and family life, identified in male and female respondants, are discussed. small changes at the personal and institutional levels can be of major significance for both men and women scientists in latin american academic institutions.

Abstract:
it seems paradoxical to commission nearly 900 proposals from all around the globe in order to create a regionally identifiable architecture. east countries, however, by means of a large number of architectural competitions, assumes as a global problem the needs of a specific place. this award-winning project is the result of such a renewed and foreign outlook on the housing policies of a local government.

Abstract:
at present, many researchers, students and university professors have the possibility to develop their writing process using new technologies. based on this reality, this work offers a didactic proposal to develop the writing process of students, university professors participating in in-service teaching process, supported on the constructivism and in the writing as process. this proposal consists of rewriting electronic academic texts using the tools that microsoft office？ offers and the e-mail to develop the writing process, to strengthen the multidisciplinary rewriting process and to develop the competence as text producers. in conclusion, it is essential to enable writers in learning process to experience, using new technologies, the act to write as a transitive verb, to write concrete texts, with real purposes and real audience; let them perceive themselves like writers, experiencing rewriting recursively.

Abstract:
the organization of biotechnology differs across countries. the structure of the industry, the academia, and the links between these two sectors vary according to which country is studied. biotechnology is organized in venezuela mainly around the research done by special research and development units at national universities. the paper describes some of these units in order to shed light about their performance. two economic approaches are used to explain the academic production of these biotech research organizations: the technological and organizational approaches. a case study methodology is used in this research. the results can be summarized as: the percentage of researchers who are doctors is less than seventy percent in each research and development unit, funding source comes basically from the venezuelan government, strategic alliances are mainly formed between universities, performance of research and development units is mostly oriented to research but not to development . the main conclusion of this paper is that the research and development organizations are only carrying out the research function because (i) the low number of doctors, (ii) the few number of strategic alliances with the private sector and (iii) the form the research and development units finance themselves.

Abstract:
this article presents the link between the results of two studies carried out within a line of investigation which started in 2002. the first one is entitled “approximation to the construction of identities of deaf people”, and it contributes with new knowledge about external and internal mechanisms which have had an effect in the identity construction of deaf people, characterizing the school as a relevant social space in which the role of the teacher is fundamental. its results create the need for a second investigation: ‘a study on the representations created by teachers of deaf people in schools of the metropolitan region', through which a typology for an understanding of the current situation in this field is postulated.

Abstract:
the central hypothesis of this critical text is that eltit？s novels are permeated by a strategy: that of the essay, as understood in the etymological sense of the word, as an "attempt" or "experiment". nothing is definitive in these novels, neither the subject nor the discourse: the subject is always a figure in movement, in transit and the discourse constructs and reconstructs itself right before the reader？s eyes. without a doubt this is a "post-vanguard" strategy or, also, "post-modern", whose meaning the critical text tries to situate in the context of the contemporary chilean novel. even when the experimental strategy runs through all of eltit？s narrative order, the quotes privilege the novel por la patria.

Abstract:
many motor skills, once acquired, are stored over a long time period, probably sustained by permanent neuronal changes. thus, in this paper we have investigated with quantitative stereology the generation and persistence of neuronal density changes in primary motor cortex (mi) following motor skill learning (skilled reaching task). rats were trained a lateralised reaching task during an "early" (22-31 days oíd) or "late" (362-371 days oíd) postnatal period. the trained and corresponding control rats were sacrificed at day 372, immediately after the behavioural testing. the "early" trained group preserved the learned skilled reaching task when tested at day 372, without requiring any additional training. the "late" trained group showed a similar capacity to that of the "early" trained group for learning the skilled reaching task. all trained animáis ("early" and "late" trained groups) showed a significant ínter hemispheric decrease of neuronal density in the corresponding motor forelimb representation área of mi (cortical layers ii-iii)

Abstract:
this paper continues the statistical analysis of a coffee varietal trial at campinas (1, 2, 3), utilising the data of a further period of 4 years. variety d (yellow bourbon) has now drawn significantly ahead of c (bourbon) as is shown by fig. 1 compared with fig. 2b of reference (3). this possibility was foreseen at the time of the earlier analysis (3), from a consideration of the annual rates of increase of yield. this is of interest to the general problem of selection of perennial plants, because it shows that not only average yield but also rate of increase of yield is a useful criterion for selection.
